Tested with the following-:

1. RedHat-release-virtualization-host-4.2-2.1.el7.x86_64
2. Cockpit-ovirt-dashboard-0.11.20-1

Lvm cache device was attached to the thinpool during the creation of bricks from the storage device. Following were the steps performed to test:-

1. Login to the cockpit UI and in gluster deployment configure hosts,package and 
   volume tabs.

2. Configure the brick tab . Configure the LVM cache with the size and proceed to 
   gluster deployment.

3. Gluster deployment was successful. Could see the LVM cache attached to the 
   thinpool during the creation of bricks from the storage device.
